just do fs.readFile and use .split('\n')
novel dagger
just do `fs.readFile` and use `.split('\n')`
whats a better ide for js, vscode or intellij?
novel dagger
just do `fs.readFile` and use `.split('\n')`
like ```js
const fs = require('fs');
let line = fs.readLine("finishedWordList.txt")
let splittedLines = line.split("\n")
console.log(splittedLines)
the as is pretty unexpected, also readLine is readFile, also it is async, so you need to put the other stuff in a callback
or you could use readFileSync if you want it sync

is there a way in vscode to show the functions for fs
dim ridge
is there a way in vscode to show the functions for `fs`
no, but you dont rly need to just search it up
fs.readFile('theFile.txt','utf-8',function(err,data) {
if (err) throw err;
console.log(data.split('\n'))
})
this still returns an empty list outside the function, inside it it works

you can use readFileSync tho, but you gotta search it up for that one
found an example
const fs = require('fs');
try {
const data = fs.readFileSync('/Users/joe/test.txt', 'utf8');
console.log(data);
} catch (err) {
console.error(err);
}
